I sent Keystone State Testing my resume several months ago. On Tuesday the CEO sent me an e-mail inviting me to an interview for that Thursday. I said I was available Thursday and he picked a time that he was free and was most convenient for him. On Thursday I rang the bell to the company's main door and five minutes later a girl in a lab coat came out and told me the CEO was busy with something at the moment, asked if I would mind waiting in my car for "a few minutes," and the CEO would be out to get me. That was fine, especially as security seemed very tight. There was a thick solid door with no windows on the door or anywhere on the building, and just a doorbell. There didn't even look to be a place for employees to scan in and I figured there may not be a lobby. I waited for an hour and a half before going back up to the building, ringing the bell, and asking if it would be more convenient for him to reschedule. The same girl told me "Um, yes...shoot him an e-mail?" I was let to sit in the parking lot for an hour and a half, waiting for an interview that would not happen, while the CEO had to know he was busy and was not able to meet with me, yet made no attempt to send someone out or e-mail me to convey that information. Although I can appreciate things come up I would also like to reiterate the interview was scheduled at a time of his specific choosing. This is extremely unprofessional, rude, and inconsiderate of my time. It is unacceptable to behave this way if you hope to have employees. I have to imagine it's telling of how the company behaves towards existing employees. Though I previously had a very positive perception of Keystone State Testing, even if I was contacted to reschedule I would not consider working for this company.
